The Device → GPI and Device → GPO tabs appear for all devices that support General Purpose Inputs and Outputs. They can be used to view (and edit) the streaming connections for the device's GPIO interfaces.
The operation is similar to that of the Stream Routing page, except that these tabs show only the connections from a single device. The example below shows the GPI tab. The method for GPOs is identical (but select the GPO tab).
1. To view all of the connections from the device, click on GPIO Routing.
The list shows all of the device's GPI "Sources" (on the left) and the GPO "Destinations" (on the right).
- If a destination is connected, then the source label appears in the "Connected Source" column. If the source is also in view, then a solid line appears.
- If a source is connected, then a number appears in the "source used" column. This indicates the number of connections made. i.e. the number of times a source is used.
2. If a GPI is connected, then it can be interrogated as follows: select a source and click on Show Destinations.
The view updates to show only the destinations of the selected source (or sources).
3. Click on Done to exit the "Show Destinations" view and return to the list of all sources and destinations.
